Risk levelLow

0–100, higher is better. How it is calculated

Sedition Ltd operates a sophisticated digital art platform specializing in curated digital limited edition artworks from world-renowned contemporary artists. The platform serves both individual collectors and businesses, offering digital art sales, subscription-based access to artworks (Art Stream), and tailored art displays for commercial venues. The company maintains strong partnerships with leading global brands and museums, reinforcing its market position as a trusted digital art marketplace. Technically, the website employs modern web technologies including React, JWPlayer, and integrates multiple analytics and marketing tools such as Google Tag Manager, Facebook Pixel, and Klaviyo, indicating a mature digital infrastructure. Security measures include HTTPS enforcement, reCAPTCHA on forms, and GDPR-compliant cookie consent mechanisms, reflecting a solid security posture. However, the absence of WHOIS registration data introduces uncertainty regarding domain legitimacy, which slightly impacts overall trust. Strategic recommendations include enhancing security header transparency and publishing a vulnerability disclosure policy to further strengthen security and trust.

This scan rated NIS2 with an earlier keyword method that is no longer shown; rescan for the per-article view. Risk management, continuity, supply chain, training, MFA, management oversight (Art. 20) and incident reporting (Art. 23) need internal evidence, and Guard cannot tell whether NIS2 applies to this organisation.

GDPR is indicative only, based on publicly visible signals: Articles 7, 12, 13 and 32 of Regulation (EU) 2016/679 and Article 5(3) of the ePrivacy Directive. Not a certification or legal assessment.

Priority findings

3 findings rated critical or high. Fix these first.

  1. Security headers

    Security headers are instructions your web server sends to every visitor’s browser. Missing ones leave visitors more exposed to attacks such as clickjacking and injected scripts.

    • High

      Missing Content-Security-Policy header

      Controls resources the browser is allowed to load

      What to do: Implement a Content-Security-Policy appropriate for your application

      • ASVS V3.4.3
      • OWASP Secure Headers: OWASP Secure Headers Project recommends Content-Security-Policy: default-src 'self'; form-action 'self'; base-uri 'self'; object-src 'none';…

  2. GDPR outside view

    These are the privacy signals visitors and data protection authorities look for under GDPR.

    • High

      No Cookie Policy found

      GDPR requires clear information about cookie usage

      What to do: Add a dedicated cookie policy explaining cookie usage and purposes

  3. SSL/TLS

    TLS encrypts the connection and proves the site is really yours. Weak or expiring certificates trigger browser warnings and put traffic at risk.

    • High

      Weak Protocols Supported

      Server supports weak protocols: TLSv1.1

      What to do: Disable TLS 1.0, TLS 1.1, and all SSL versions

      • CWE-327
      • OWASP A04:2025
      • ASVS V12.1.1

Results by check

Each check with its score, findings and the evidence it collected.

How this score is calculated

The security score runs 0–100, higher is better. It is the plain average of the security checks that completed in this scan, each counted equally. A check that could not run is left out: it counts neither as a pass nor as a fail.

Not counted

  • NIS2 outside view: Re-weights evidence from the TLS, email, DNS, network and hygiene checks, so counting it would count that evidence twice. Shown on its own.
  • OffSeq Observations: An AI reading of the site, useful context but not reproducible evidence. Shown on its own.

Findings that cap the score at 49

Each of these is serious on its own, so while any is present the site cannot rate better than high risk, however good the other checks are.

  • The certificate is not trusted by browsers
  • The website is not served over HTTPS
  • A database, remote desktop, file-sharing or Telnet service is reachable from the internet
  • The page loads a script from a compromised source
  • The domain registration has expired
  • SPF authorises every server to send mail as the domain

Partial scans

When the site blocks Guard or most checks cannot run, the score covers only the checks that ran (usually DNS and email), is capped at 75 and is shown as partial, without a risk level.

Technical appendix

Business context, site observations and technical notes gathered during the scan, and the standards behind each reference.

Business context

Business profile

Sedition Ltd targets digital art collectors and businesses seeking innovative art display solutions, leveraging a subscription model alongside direct sales. Its competitive advantage lies in exclusive artist partnerships, a curated collection, and integration with physical display technologies like Muse Frame. Revenue streams include artwork sales, subscriptions, and business licensing. The company demonstrates growth through active marketing, social media presence, and collaborations with prestigious brands. The platform's ecosystem includes partnerships with OpenSea and major hospitality and technology companies, enhancing reach and credibility. Operationally, the company exhibits professionalism and a consistent brand image, supporting sustained market relevance.

Security posture

The website demonstrates a mature security posture with HTTPS, secure authentication forms protected by CSRF tokens, and use of reCAPTCHA to mitigate spam and abuse. GDPR compliance is evident through cookie consent banners and privacy policies. No critical vulnerabilities or exposed sensitive data were detected. However, the lack of explicit security.txt or incident response contact information limits transparency in vulnerability management. Security headers appear partially implemented but could be explicitly confirmed and enhanced. Overall, the security maturity is good but can be improved with clearer incident response and disclosure practices.

Recommendations

  1. Publish explicit security headers such as X-Frame-Options and X-Content-Type-Options to enhance browser security.
  2. Implement and publicly link a security.txt file to facilitate responsible vulnerability disclosure.
  3. Enhance visibility of incident response contacts to improve trust and readiness.
  4. Regularly audit third-party scripts and libraries to ensure no vulnerabilities are introduced.
  5. Maintain and update privacy and cookie policies to reflect evolving regulations and best practices.

  2. Strong presence of digital art marketplace features and artist profiles.
  3. Multiple trusted brand partnerships and museum affiliations.
  4. Comprehensive privacy and terms policies present.
  5. Use of modern web technologies and analytics tools.
  6. No signs of WAF or blocking mechanisms.

Technical notes

Notes

The website is built on a modern React-based frontend with integration of multimedia playback via JWPlayer and payment processing through Stripe. It leverages multiple third-party analytics and marketing services, including Google Tag Manager, Facebook Pixel, LinkedIn Insight Tag, Twitter Ads, and Klaviyo, indicating a comprehensive data-driven marketing approach. Performance is moderate with good mobile optimization and accessibility features. The site uses asynchronous script loading and CDN-hosted assets to optimize load times. No CMS was explicitly detected, suggesting a custom or proprietary platform. Technical risks include dependency on multiple external services which require ongoing monitoring for security and privacy compliance.
Standards and sources

Reference chips under each finding point to the standard, regulation or specification the finding relates to. They are taken from the official datasets below and mapped conservatively: a finding with no defensible link shows none. NIS2 and GDPR references mark where a finding is relevant evidence, not a compliance verdict. Implementing Regulation (EU) 2024/2690 binds digital infrastructure and digital service providers; for other entities it is the most detailed public reading of the Article 21 measures. WCAG, EN 301 549, European Accessibility Act and Web Accessibility Directive references name the requirement an automated accessibility rule relates to; they are not a conformance verdict.
